Before today, U.S. adults had remained fairly consistent in their religious beliefs — 82% of U.S. respondents previously reported that they believed there was a God since 2005.

In another decline, only 54% of Americans are now "absolutely certain" in God's existence, a 12% decrease over the last decade.

Not all of us feel this way. The groups most likely to be certain of God's existence are Black Americans (70%), Republicans (65%), Baby Boomers (60%), Southerners (61%), and Midwesterners (58%), as well as anyone with a high school education or less (60%).
